Definitions

  • the present invention relates to a new reliable means for measuring the total duration of the wearing of a removable orthodontic appliance (unimaxillary or functional) - hereinafter referred to as "removable appliance” ( Fig. 1 ) - worn by a patient for a period of time very specific.
  • removable appliance Fig. 1
  • This device is intended to explore by the attending physician the regularity of the wearing of the removable device.
  • US 4729948 discloses an indicator paper for the measurement of amylase activity, said indicator paper being composed of a single main zone initially stained with iodine tincture.
  • the new invention is based on the use of an indicator paper ( Fig. 2 ) inserted by the attending physician in the removable apparatus and exposed to the salivary medium.
  • the insertion of this paper is done in an open window ( Fig. 1, No. 1 ) specially designed by the dental technician when designing the removable device. Under the effect of the contact of the indicator paper with the saliva, the paper will undergo a gradual fading depending on the duration of the presence of the device in the oral cavity.
  • a starch-rich paper will be selected and will be stained by iodine dyeing in violet under the effect of starch presence.
  • the discoloration of the indicator paper will occur during the reaction of saliva with the starch present in the paper. This discoloration results from an enzymatic degradation under the action of a salivary enzyme, called "amylase", which degrades the starch present in the indicator paper.
  • amylase a salivary enzyme
  • the indicator paper can only fade by saliva and remain unchanged (no discolouration) in contact with any other liquid flow. or food.
  • the indicator paper must be permeable to salivary flow.
  • the indicator paper will be designed previously in the form of a purple intensity gradient, visible in distinct, contiguous areas of the same width ( Fig. 2 ) .
  • the number of these areas is based on the desired length of time between the patient's check-ups. For example, for removable orthodontic treatment requiring patient follow-up every four weeks, the attending physician will use a four-zone indicator paper ( Fig. 2 ). If the follow-up interval is set every six weeks, a six-zone indicator paper will be used in its place.
  • the indicator paper will be removed by the physician for examination and measurement of the wearing time of the removable device.
  • the old indicator paper will be replaced by a new paper.
  • the indicator paper is composed of several main zones of purple color which are initially colored with tincture of iodine of different concentration and which are juxtaposed in gradient. Under the chemical effect of saliva on the indicator paper, there will be a gradual fading by area. Depending on the number of discolored areas, we will deduce the total effective time of the wearing of the removable device in the oral cavity between two consultations.
  • Area No. 1 This area corresponds to regular port (eg, 20 hours per day) of the removable device for a week. It is colored iodine tincture of a sufficient concentration C 1 so that the area is completely discolored after one week.
  • Zone number 2 this zone corresponds to the regular port of the removable device for two weeks. It is colored iodine tincture with a sufficient concentration C 2 so that the area is completely discolored after two weeks.
  • Zone number 3 this zone corresponds to the regular port of the removable device for three weeks. It is colored iodine tincture of a sufficient concentration C 3 so that the area is completely discolored after three weeks.
  • Zone number 4 this zone corresponds to the regular port of the removable device for four weeks. It is colored iodine tincture of a sufficient concentration C 4 so that the area is completely discolored after four weeks.
  • the first area After one week of regular wearing of the removable device, the first area will be completely discolored. For the other three zones, each will be clearer than before.
  • zone number 2 will also be totally discolored, and zones number 3 and 4 will each be even clearer. So, at the end of the fourth week, if the device has always been worn, no colored areas should remain.
  • each main zone can be further subdivided beforehand and visualized by the distinct color intensity which remains lower than that of the main zone. next.

Claims (7)

  1. Indikatorpapier zum Messen der Tragedauer einer herausnehmbaren kieferorthopädischen Apparatur, wobei das Indikatorpapier für den Speichelfluss durchlässig, mit Stärke versehen und anfänglich mit lodtinktur derart gefärbt ist, dass es durch enzymatischen Abbau der Stärke unter der Wirkung der Amylase entfärbt werden kann, dadurch gekennzeichnet, dass das Indikatorpapier aus mehreren Hauptzonen besteht, die anfänglich mit lodtinktur in unterschiedlicher Konzentration gefärbt und abgestuft nebeneinander gelegt werden.
  2. Indikatorpapier nach Anspruch 1, wobei die Hauptzonen getrennt, aneinandergrenzend und von gleicher Breite sind.
  3. Indikatorpapier nach Anspruch 1 oder 2, wobei die Anzahl der Hauptzonen je nach der gewollten Dauer des Intervalls zwischen den Kontrollkonsultation gewählt sind
